The immiscible displacement of a wetting fluid by a non-wetting one in heterogeneous porous media is modeled by using a multi-scale network-type analysis: (1) The pressure-controlled immiscible displacement of water by oil in pore-and-throat networks (length scale~1mm) is controlled by capillary forces. (2) The pressure-controlled immiscible displacement in uncorrelated or spatially correlated ...

It has been proved that ultrasonic energy can considerably increase the amount of oil recovery in an immiscible displacement process. Although many studies have been performed on investigating the roles of ultrasonic waves, based on the best of our knowledge, little attention has been paid to evaluate wave attenuation parameter, which is an important parameter in the determination of the energy...

One standard way of forming monolayers (MLs) of nanoparticles (NPs) is to drop-cast a NP dispersion made using one solvent onto a second, immiscible solvent; after this upper solvent evaporates, the NP ML can be transferred to a solid substrate by liftoff. We show that this previously universal use of only immiscible solvent pairs can be relaxed and close-packed, hexagonally ordered NP monolaye...

In this paper, we investigate the wellposedness of nonisentropic compressible Navier–Stokes/Allen–Cahn system with heat conductivity proportional to a positive power temperature. This describes flow two-phase immiscible heat-conducting viscous mixture. The phases are allowed shrink or grow due changes density in fluid and incorporates their transport current. We established global existence uni...

Being a lithophile element at ambient pressure, magnesium has been long believed to be immiscible with iron. Authors of recent study showed that pressure turns into siderophile and can produce unconventional Fe-Mg compounds [Gao et al., New J. Chem. 43, 17403 (2019)]. Here, we extend the investigation exoplanetary conditions using an adaptive genetic algorithm-based variable-composition structu...

Abstract. Ultra-severe plastic deformation (ulta-SPD) is a terminology used for the introduction of extremely large shear strains (over 1000) to material so that thickness sheared phases geometrically reaches subnanometer level. Under such extreme shearing conditions, new nanostructured with unique properties are formed even from immiscible systems. Various metallic alloys and ceramics were dev...

Janus-like W-Cu films exhibiting a tilted columnar architecture are prepared by GLAD co-sputtering using W and Cu targets. Co-deposition of these two-immiscible metals leads to contrasted morphologies in the columns growth. Observations scanning electron microscopy reveal different structural features at micro- nanoscales as face or target. In front flux, dense with saw-tooth profile, whereas g...

A novel and environmentally benign approach is described to combine reactions and separations, using simultaneously ionic liquids (ILs) and supercritical carbon dioxide (SCCO2). The novel approach is based on the phenomenon that two (partially) immiscible liquid phases upon pressurization with CO2 is able to force to form one homogeneous fluid phase. The homogeneous phase allows reactions to be...

We compare two recently developed mesoscale models of binary immiscible and ternary amphiphilic fluids. We describe and compare the algorithms in detail and discuss their stability properties. The simulation results for the cases of self-assembly of ternary droplet phases and binary water-amphiphile sponge phases are compared and discussed. Both models require parallel implementation and deploy...
